- πΈπ°Slovakia poker10Thanks for reporting and working on this. xmlsitemap_schema()does not setlanguagecolumn in the primary key. So the question is, how you ended with that column included in the primary key? I installed the latest 7.x-2.x on Drupal 7.101 and checked with the Schema module if there are any warnings - but there are none. We will not add a new column to the PK without knowing the reason how it appeared there. Feel free to reopen this if you have a steps to reproduce how to achieve thelanguagecolumn in the primary key of thexmlsitemaptable. Thanks!
